Abstract (en)

A data transfer system is configured such that data collision detection and data transmission are performed using different lines to eliminate the need for employing a wired-OR circuit, or the number of reception buffers to be employed is reduced. These arrangements make it possible to realize a high-speed serial bus with reduced power consumption. <IMAGE>
